What anatomy is identified during bronchoscopy?
the trachea is D shaped, the flat wall is posterior. the RML bronchus is anterior. the apical (aka superior) segmental bronchi of the lower lobes are posterior. if in doubt, go back to the carina.
What is right upper lobe bronchus?
The right upper lobe bronchus is given off approximately 2.5 cm from the bifurcation of the trachea and is the superior most of the secondary bronchi 1. It transverses the right hilum into the right upper lobe where it divides into three bronchopulmonary segments that supply the superior lobe of the right lung 2.
Where is the right upper lobe in the lungs?
The right upper lobe of the lung is located in the right superior corner of the thoracic cavity lateral to the trachea and esophagus. It is superior to the horizontal and oblique fissures, which separates the upper lobe from the middle and lower lobes of the right lung.
What is the upper lobe of a lung?
The upper lobe is the largest lobe of the right lung. It extends from the apex of the lung down to the horizontal and oblique fissures. It bears apical, anterior, and posterior bronchopulmonary segments.
What is upper right lobe?
The right upper lobe (RUL) is one of three lobes in the right lung. It is separated from the right lower lobe by the oblique fissure and the middle lobe by the horizontal fissure and subdivided into three bronchopulmonary segments.
What is right lower lobe?
The right lower lobe (RLL) is one of three lobes in the right lung. It is separated from the right upper lobe superiorly and the middle lobe anteriorly by the right oblique fissure and is subdivided into five bronchopulmonary segments. Article:
What is the middle lobe of the lung?
On the mediastinal surface of the lung, it may be traced backwards to the hilum. The middle lobe is the smallest of all the lung lobes of the right lung. It is wedge-shaped and includes the lower part of the anterior border and the anterior part of the base of the lung.
What is a lung lobe?
lobe of the lung – any of the three lobes of the right lung or the two lobes of the left lung lung – either of two saclike respiratory organs in the chest of vertebrates; serves to remove carbon dioxide and provide oxygen to the blood lobe – (anatomy) a somewhat rounded subdivision of a bodily organ or part; “ear lobe”
